Reading File In Python

To read a text file, use:
fp = open("file.txt","r");
print fp.read()

For writing to a file, use:
fp = open("data.txt","w");
write("Hello World");
fp.close();

C++ Template Function

Templeate function used for flexibility of the type. So you can do programming like in scripting language. See this code:

templace

myType getMin( myType a, myType b){   

   if(a

        return a;

   }else{

        return b;

   }

}

The you call it by:

int x = 2;

int y = 3;

int c = getMin(x,y);

cout << c << endl;

output>> 2

You can use this function for long data type:

long x = 456789;

long y = 456788;

int c = getMin(x,y);

cout << c << endl;

output>> 456788

More example:

template

Lol addTwo(Lol x){

    Lol r = x + 2;

    return r;

}

then call it by

cout << addTwo(2) << endl;

output>> 5
       
For using two kind of different data type, use

template

A addTwo(A a, B b){

     A r = a+b;

    return r;

}

then call it by:

int x = 4;

long y = 45;

cout << addTwo(x,y) << endl;

output>> 49

Iterating Method In Java

For a given array, to iterate over the whole elements in the array, use:

String[] names = new String[]{"lady gaga","barack obama","larry page"};

for(String s: names){

    System.out.println(s);

}

output:

lady gaga

barack obama

larry page

Batch Basic

Batch file is a file that consift of DOS command. What you can do in command prompt, will also can be done in batch file. Type this code in hello.bat, and then execute it with

C:\hello.bat lady gaga

@ECHO OFF

ECHO hello, %1

To make a variable, type:

SET name=Lady Gaga

echo %name%

PAUSE

IF Statements:

@ECHO OFF

SET a=luna

SET b=luna

IF %a%==%b% GOTO luna

ECHO Sorry, Lady!

:luna

ECHO You may win, Luna!

Procedure In Pascal

Here's a code on how write a procedure in Pascal:

Without Parameters

Program UsingProc;

uses wincrt;

procedure hello;

var

    name : string;

begin

    name := 'lady gaga';

    writeln(name);

end;

begin

    hello;

end.

With Parameters:

Program UsingProcParam;

uses wincrt;

procedure hello(name : integer);

begin

    writeln(name);

end;

begin

    hello('lady gaga');

end.

Looping In Pascal

Here's a code on how to loop over a number of times;

For Loop:

Program forLoop;

uses wincrt;

var

    i : integer;
    c : char;

begin

    

    for i := 0 to 100 do

    begin

        writeln(i,'. Holla World');

    end;

    writeln('==========================');

    for i := 100 downto 10 do

    begin

        writeln(i,'. Holla World Again');

    end;

    writeln('===========================');

    for c := 'a' to 'z' do
    begin
        writeln(c,'. characters');
    end;

end.

While Loop:

Program whileLoop; 

uses wincrt;

var

    i : integer;

begin

    i := 0;

    while i<100 do

    begin

        writeln(i,'. Less than 100');

        i := i+1;

    end;

end.

Repeat Until

Program untilLoop;

uses wincrt;

var 

    i : integer;

begin   

    i := 1;

    Repeat

        writeln(i,'. Holla World');

        writeln('This holla comes from turbo pascal');

        i := i + 1;

    until i = 100;

end.

If Else In Pascal

Here's a code on how to write a decision programs.

Program Sleeping;

uses wincrt;

var

    sleep : boolean;

begin

    sleep := true;

    if (not sleep) then

    begin

        writeln('Lady gaga still sleep');

        writeln('So please keep silent');

    end

    else

    begin

        writeln('You can do what you want');

        writeln('And this is a free area');

    end;

end.
